Traxxas Gear Set 2-Speed Close Ratio 40T Second Gear 13T-16T Input Gears TRX5383

Overview

The Traxxas Gear Set, 2-speed close ratio (TRX5383) is an essential drivetrain upgrade for Traxxas Revo and Slayer RC cars, delivering a complete replacement gear set engineered to transform your vehicle's performance characteristics. This is a specialist component designed for experienced RC enthusiasts who want to fine-tune their transmission ratios for specific driving conditions. Whether you're a serious hobbyist looking to optimise your RC car UK setup or a competitive racer seeking the perfect gear configuration, this close ratio gear set provides the precision engineering that Traxxas is renowned for throughout the remote control hobby community.

What makes the Traxxas 2-speed close ratio system unique is the ability to custom tailor your transmission's performance through interchangeable gear ratios. Unlike many ready-to-run RC vehicles that come locked into a single gear configuration, the Revo and Slayer platforms offer flexibility that lets you adapt your drivetrain to match your driving style and terrain. The close ratio configuration reduces the engine's RPM change between first and second gear, enabling nearly seamless shifting and consistent speed delivery even through tight corners. This means smoother acceleration curves, more predictable handling behaviour, and a driving experience that feels refined rather than aggressive.

This gear set represents genuine OEM Traxxas engineering, manufactured to the exact specifications that ensure compatibility and reliability with your vehicle's transmission system. The components have been precision-engineered to work seamlessly with your existing drivetrain, providing an authentic upgrade path that maintains the integrity of your RC car whilst delivering measurable performance gains.

Key Features

• 2-Speed Close Ratio Configuration — This gear set implements a close ratio design that minimises the RPM differential between first and second gear shifting, which means your engine maintains more consistent power delivery across gear changes and enables smoother cornering speed maintenance that wide-ratio setups cannot achieve.
• 40T Second Speed Gear — The 40-tooth second speed gear is the primary component that defines this set's close ratio characteristics, working with the input gears to create a transmission ratio optimised for seamless speed transitions.
• 13T-16T Input Gears — The set includes a range of input gears (13 to 16 teeth) that allow you to fine-tune your first gear ratio based on your specific driving conditions, terrain type, and performance preferences.
• Complete Hardware Package — Every fastener, bearing, and mounting component required for proper installation is included, eliminating the need to source additional parts and ensuring you can complete the upgrade without delays.
• OEM Traxxas Quality — As genuine Traxxas parts, these gears are manufactured to factory specifications using the same materials and precision tolerances as original equipment, guaranteeing compatibility and reliability.
• Revo and Slayer Platform Compatibility — Specifically engineered for Traxxas Revo and Slayer vehicles, this set represents one of the few drivetrain upgrade options that lets you move beyond the standard wide ratio configuration these models come with as stock.
• Performance Optimisation Without Modification — Installing this gear set requires no permanent modifications to your vehicle; you can switch between ratio configurations simply by changing gear sets, making experimentation and tuning accessible to dedicated enthusiasts.

Technical Performance

The Traxxas Gear Set TRX5383 is engineered with precision-cut gears manufactured from hardened steel, the industry standard for RC drivetrain components due to its superior wear resistance and durability under the stresses of repeated acceleration, deceleration, and cornering loads. The close ratio design represents a middle ground in transmission tuning philosophy: it provides smoother power delivery than wide ratio setups (which are stock on most Traxxas vehicles) whilst offering greater overall durability and less thermal stress than extreme high-speed ratios designed purely for top speed running on hard surfaces. The 40-tooth second speed gear works in concert with the supplied 13T-16T input gears to create gear ratios that maintain engine efficiency across a wider RPM band, reducing the abrupt torque spike that occurs during traditional gear changes in stock-ratio vehicles. This engineering approach means your motor experiences more consistent load conditions, reducing heat generation and extending component lifespan compared to vehicles run with mismatched gear ratios. The complete hardware package ensures proper bearing support and gear mesh alignment, critical factors that determine drivetrain efficiency and longevity. For RC car enthusiasts in the UK seeking to balance performance with reliability, this gear set represents a thoughtful engineering solution that acknowledges real-world driving demands rather than chasing single-axis performance metrics.

Frequently Asked Questions

• What is the difference between close ratio and standard ratio gears for RC cars? — Close ratio gears reduce the RPM change between first and second gear, creating nearly seamless shifting and more consistent speed delivery, particularly beneficial in cornering situations. Standard wide ratio gears offer greater torque multiplication in first gear but create a more pronounced shift feel. The close ratio configuration suits drivers who value smooth, predictable handling over aggressive acceleration.
• Which Traxxas vehicles is the TRX5383 compatible with? — This gear set is specifically designed for Traxxas Revo and Slayer RC vehicles. These platforms are among the few Traxxas models that offer the ability to swap between close and standard ratio configurations, making them genuinely tunable systems for dedicated enthusiasts.
• Do I need any special tools to install this gear set? — The source material does not specify tools required. We recommend consulting your vehicle's manual or contacting our team of experienced RC enthusiasts at RC Model Shop for installation guidance and support.
• How will close ratio gears affect my vehicle's top speed? — Close ratio configuration reduces the performance spread between first and second gear, meaning you'll achieve top speed more gradually than with wide ratio gears, but with more predictable acceleration and better handling through corners where traditional wide ratio setups might lose traction.
• Is this upgrade suitable for beginners? — This product is best suited to experienced RC hobbyists who understand drivetrain tuning concepts and feel confident performing mechanical upgrades. Beginners new to the RC hobby in the UK should first master their vehicle with stock gearing before exploring ratio modifications.
• What makes Traxxas gear sets different from aftermarket alternatives? — Genuine Traxxas components are engineered to OEM specifications and manufactured using factory-approved materials and processes, ensuring perfect compatibility with Revo and Slayer transmissions whilst maintaining reliability standards. Traxxas is a recognised leader in RC vehicle engineering with decades of development invested in drivetrain optimisation.
